Problems solved by technology

[0005] ① When burning chlorinated organic substances and aromatic hydrocarbons, it is very easy to produce dioxins, which are strong carcinogens, especially during the start-up and shutdown of the incinerator
[0006] ② There is a potential danger of explosion when burning, especially volatile combustible gas, if it reaches its explosion limit and encounters an open flame, it may cause an explosion
[0007] Catalytic combustion (CO) and regenerative catalytic combustion (RCO) have no open flame, and the reaction temperature is generally 300-500°C. Dioxins, strong carcinogens, are also produced when chlorinated organic substances are treated; but when the exhaust gas contains sulfur elements It will cause problems such as catalyst poisoning and deactivation, which limits the promotion and use of this method to a certain extent.

Abstract

The invention belongs to the field of organic waste gas treatment methods, and relates to organic waste gas treatment equipment and a use method, in particular to a high-concentration organic waste gas treatment system and an organic waste gas treatment method. The system comprises an activated carbon box A and an activated carbon box B. The desorption process of the activated carbon box A and the activated carbon box B comprises a desorption air inlet end and a desorption air outlet end, the desorption air outlet end is communicated with the air inlet end of an internal combustion engine, the air outlet end of the internal combustion engine is communicated with a heat pipe of a heat exchanger, and the heat exchanger is provided with an air inlet which is communicated with a cold pipe. The cold pipe is communicated with the desorption air inlet end of the internal combustion engine, valves are installed at the adsorption air inlet ends, the adsorption air outlet ends, the desorption air inlet ends and the desorption air outlet ends of the activated carbon box A and the activated carbon box B respectively, and any one of the activated carbon box A and the activated carbon box B can be adjusted to be in an adsorption state and the other one to be in a desorption state through the valves.

Description

Technical field[0001]The present invention belongs to the field of organic exhaust gas treatment, and is involved in organic exhaust gas treatment equipment and methods of use, in particular, a high-concentration organic exhaust gas treatment system and an organic exhaust gas treatment method.Background technique[0002]High-profile, low concentration industrial VOCS multi-adsorption concentration and combustion combined treatment.[0003]The adsorption concentration process adsorbent generally uses activated carbon. When the activated carbon sucks saturated, it is combusted after evaporation of water vapor or nitrogen. Nitrogen as a high operating cost of the dense medium, and the water vapor produces wastewater as a dense medium desorption process, causing secondary pollution, and after desorption is completed, activated carbon takes a long time to cool dry to use again.[0004]The combustion method is mainly divided into direct combustion (TO), catalytic combustion (CO), heat storage c...
